-* NXP PCA9541 I2C bus master selector

-Required Properties:
-
-  - compatible: Must be "nxp,pca9541"
-
-  - reg: The I2C address of the device.
-
-  The following required properties are defined externally:
-
-  - I2C arbitration bus node. See i2c-arb.txt in this directory.

-Example:
-
-	i2c-arbitrator@74 {

-		reg = <0x74>;
-
-		i2c-arb {
-			#address-cells = <1>;

-
-			eeprom@54 {
-				compatible = "atmel,24c08";
-				reg = <0x54>;
